Good day, i have a RAK7258 Gateway and would like you use the built in network server and MQTT broker. How do I subscribe to topics using the IP address in Node-Red? The gateway is not local. Thanks!

Hi @lloyd.green.31
The RAK7258 is an old model and it uses WisGateOS version 1. If the gateway is not local my recommandation is to set up a VPN tunnel to the server where you are running NodeRED. You can find the instructions on how to use OpenVPN on WisGateOS here: OpenVPN Configuration | RAKwireless Documentation Center
Once the gateway is connected you will be able to access the MQTT broker in the gateway using it’s IP address in the tunnel.
